A servo system consists of a servo driver and a servo motor. The driver utilizes precise feedback combined with a high-speed digital signal processor (DSP) to control IGBTs to generate precise current output, which drives a three-phase permanent magnet synchronous AC servo motor to achieve functions such as precise speed regulation and positioning. Compared with ordinary motors, AC servo drivers have many internal protection functions, and the motors have no brushes or commutators, making them more reliable and requiring less maintenance.
To extend the service life of the servo system, the following points should be noted during use. The operating environment of the system must consider five factors: temperature, humidity, dust, vibration, and input voltage. The cooling and ventilation system of the CNC device should be cleaned regularly. The operation of each cooling fan on the CNC device should be checked frequently. Depending on the workshop environment, the system should be inspected and cleaned every six months or quarter.
Even when CNC machine tools are idle for extended periods, regular maintenance of the CNC system is still necessary. First, the CNC system should be powered on frequently, allowing it to run unloaded with the machine locked. During the rainy season when humidity is high, it should be powered on daily to allow the heat generated by the electrical components to drive away moisture inside the CNC cabinet, ensuring the stable and reliable performance of the electronic components. Experience has shown that machine tools that are frequently idle are prone to various malfunctions when turned on after the rainy season.
Due to limitations in the working conditions of end users of motion control systems and the engineering and technical support capabilities of enterprises, electromechanical systems often cannot be well managed. This can result in either a shortened life cycle of mechatronic equipment or, in severe cases, reduced production capacity and economic losses due to equipment failures.
